From video to series of images
The creation process should start with a transparent .MOV file supplied by the client. In Adobe Photoshop open the transparent .MOV:
Add a Solid Color adjustment layer under the video layer:
Move it under the Video Group and make the timeline equal to the video one:
Sample the color of the Color Fill layer until the edges of the the solid content of the video blend:
With these in place render a video as uncompressed quicktime at the resolution of the final images but at the video’s native frame rate to avoid interpolating. Use powers of 2 for the width and height values but keep a note of the original video aspect to use for the model.
After apply Color Overlay Layer style both to the Video layer (color must be white #FFFFFF) and the Color fill (color must be black #000000). Export a similar video for alpha.
To generate the image sequence open Adobe Media Encoder and drag the 2 videos into the queue and select .JPG as format (if you don’t have JPG as an option install Adobe Premiere)
The encoding settings are as follows but frame rate can vary from 2 to 12 FPS:
Name the files for example Video_ and Video_A_ to denote color and alpha and create a new folder for the files and press the green play button to process the queue:
Remember that the alpha and color can have different resolutions but not different frame rates.
